SLITTING MACHINE.

Application filed July 10, 1925. Serial No. 42,673.

My invention relates 'to slitting machines and hasfor its object toprovidc a machine of novel construction for slitting tubular materiallengthwise in an elilcientand continuous manner. My; invention contenuplates particularly the provision of a inachine for rapidly slittingtubular fabric as it comes from a sewing machine, into flat biased.sheets. Other objects of the invention will appear from the descriptionhereinafter and the features of novelty will be pointed out in theclaims.

fn the accompanying drawings, which illustrate an example of theinvention Without defining itslimits, Fig. l isa plan view of themachine; Fig. 2 is an end elevation partly in section, looking in thedirect-ion of the arrow in Fig. l; Fig. 2 is a side elevation and Fig. lis a detail view showing the cutting mechanism. i

As shown` in the drawings the machine comprises a frame l of suitableform and dimensions and-including a horizontal bedplate ll which in theillustrated example is continued at one end beyond the frame l() in theform of a shelf 12 and bearing brackets l. In its illustratedform, themachine includes a shaft la journalled in the latter and carrying aroller l5, the surface of which is preferably roughened for instance bybeing covered Wit-h sandpaper or emery cloth to provide a good grippingsurface for the purpose to be more fully setforth hereinafter. A pulleylo' is fixed uponthe shaft la which projects beyond the one`bearing-bracket 18 for accommodating the same, said pulley beingconnected by means of a belt 17 with `apulley 18 which is mounted upon adrive shaft 19 as shown in Figs. l and 2. By a suitable arrangement ofpulleys or their equivalent, the roller l may be driven at a highersurface speed than the feed rollers 33 and 33 so that the material,after having been slit,is efficiently Withdrawn from the machine as willappear more fully hereinafter. rlhe shaft l9f`urther carries a secondpulley 20 which in turn is connected, by means of a belt`2l, withanother pulley 22 carried-by a stud-sl`iaft 23 journalled in a bearing2d; the latter is secured upon a bracket 25 projecting from the framel() as illustrated in Figs. l and 3. The shaft 19 is rotatably mountedin bearings 26 and 26a, comprising parts of stationary b `ackets 2T and2" fastened upon and projecting up- Wardly from the bed-plate ll,suitable provision being made to prevent lengthwise movement of saidshaft in said bearings Without interfering with its rotation therein.The stationary bracket 27 is continued in the forni of a horizontal arm28 provided at its free end `with a vertical bearing 29 in which anupright shaft 30 is journalled; the latter in addition is rotatablymounted in a second vertical bearing 29LL located in spaced axialregistry with the bearing 29 andforming part of a horizontal arm 3l asshown in Fig. 2. lhe arm 8l in turn comprises part of an auxiliarybracket 32 which, in the illustrated example, is an independent elementfixed upon the bracket 27. although it will be obvious that the brackets2"( and may be cast or otherwise constructed as an integral unit; in anycase, said brackets 27' and comprise an auxiliary supporting meanslocated `upon the bed-plate ll. A roller preferably having aconcavesurface is fixed upon the shaft 3l) betweenthe bearings 29 and29a, the arrangement being such that said shaft 30 is fixed againstvertical movement in said bearings but is Vfree to rotate therein. Theupright shaft $0 is actuated by means of a bevel-pinion which mesheswith a similar bevel-pinion fixed upon the driving shaft 19 as shown inFig. 2. A companion roller 33 of corresponding concave form is carriedby a second upright shaft 30a in transverse reg istry with the roller.33 as shown in Figs. l and 2, said shaft 30a being journalled invertical bearings 29 and 29c located in spaced axial registry with eachother; in the illustrated example, the bearings 22D and Lfu are carriedby upright brackets and 35, the

latter being fastened upon and supported by the former, although it willbe obvious that said Vbrackets 34; and also maybe cast or otherwiseconstructed in'the form of an integral unit. The roller 33 is locat edbetween the aforesaid bearings 29g and 29c and is fastened to the shaft30 in a. manner to prevent lengthwise movement thereofin said bearingsWithout "interfering with the rotation of said shaft therein. In anycase7 the bracket Sil projects upwardly from a carrier 3G which isslidably mounted upon a horizontal guide 37 forming part of or securedupon the bed plate ll as shown in Fig. 2, suitable devices such setscrews 38 being provided for fixing the carrier 36 mais lill r normallyforced toward tbe rolle screw 4() which projects into a key-lila): ilextending lengthwise oit the shalt l all il lustrated 111 Fig. 2; thebevel pinion -lf meshes 'With a bevel pinion 84 :tired lllloii tliesliatlt 20".

scribed 'with respect' to the spreader 46a.

Themachine is then set inmotion by means cf the pulley 63 and belt 64,vvherebymqtion is imparted to the shaft 19 and the rollers 33 `and 33a;at the same time, the cutter lis actuatedv through the 'medium of thebelt 59 and pulleys i8 and 60. `The materiali() is then fed in the`direction of its length bythe action of the rollers 33 and 33u incooperation With the rollers 42 andllithe latter serving to yieldinglypress the material against the rollers 33 `and 33`respectivcly `andbeing themselves operated by fractional engagement therewith.l its theniaterial` is thus fed along, the cutter ihwill slit the sameuntilfinally the material" is passed over and in surface engagement with theroller 15 which is driven by means of thebelt 17 and pulleys 16 and 18.The outer surface of said roller 15 being roughened by being coveredwith sand paper orthe like, it will grip the material and exerta pullthereong" because of the fact that'the roller 15 is driven at a. highersurfacespeed than that of the rollers 33 and 33a, the speed at which thematerial is fed by said rollers will be" slightly less `than the speedativhich the roller 15 tends to advance said material* As afresult ofthis, thematerial 70"islh`eld underatension or in other Words ismaintained in a tant condition between the rollers 33 and 33a and theroller 15 whereby the slitting action of the cutter 54 ismateriallyfacilitated. At

kthe same time, the material after having been slit is e'liicientlyremoved from the ma- It will be noted that at the slitting joint` thematerial 70 passes .over the forked end 62 of the guide member 61 andtha after it is slit, said material travels beneath the cross-bar 50 andgradually opens up into the flat sheet-like form in which it passes overthe roller l5. In this Way, the material is continuously fed along atthe slitting point and is progressively slit in the direction of itslength and as this slitting occurs, the material opens up flat under thecross-bar 50 as indicated in Figs, 1 and 3. The fabric or material`Filis produced in its tubular form in such a manner that when slit, theresulting flat sheets are cut on the bias. As the travel of the materialinto the machine progresses, the turn-table 65 is rotated in a mannerand at speed to progressively un twist the fabric or material as itpasses from the receptacle G9 so that the tubular matcrial passes in asmooth condition over the spreaders i6 and 46a in a uniform manner and`without interruption as long as the machine is in operation. The shelfl2 prevents i sagging of the material into the mechanism on the machineside of the roller 15 if anything occurs to interrupt the action of the`cooperation between the rollers latter. If desired, the shelfl may bepositioned in the machinet mA a manner to guide `the'slitted materialout of the machine by y gravityin which case the roller 15 and its iassociated parts may be omitted.

lThe adjustment ofthe spreaders permits the machine to accommodatetubular material `of various sizes and `atthe same "time makes itpossible to etii'ect a most eliicient y as, arr 42', 42a respectively.The latter being resiliently mounted not only exert a most efficientgripping action in the material to facilitate `the feeding action of therollers 33 and 33a but are capable of yielding `relatively to the lastnamed rollers if, in the operation of the machine, this becomesnecessary.

The machine is simple in construction and eiiicient in operation andrequires'no skilled attention in the performance of its functions. A

Various changes in the specific form shown and described may be made"within the scope of the claims without `depaiting from the spirit of myinvention.
